无法获取转储的调试符号

Cannot obtain debugging symbols for dumps

本文关键字：调试 符号 转储 获取      更新时间：2023-10-16

尝试在windbg/VS中调试迷你转储。无法获取9.0.30729.8387版本的msvcr90的符号。试图做.symfix。如果我为我的应用程序符号设置同情，我可以得到我的代码的一部分调用堆栈，但不是msvcr。如果我使用.symfix，我可以部分地从c运行时获得几个调用，但是，显然，不是从我的代码。

!sym noisy without .symfix:

我能看到的最后一件事是msvcr90!_freefls的调用。在所有的方法中，我只能得到调用堆栈的一部分，我需要全部。是否有办法获得正确的符号?9.0.30729.6871的符号也有类似的问题。

客户端操作系统:Windows Server 2012 (build 9200) 64位，Windows 7 (build 7600) 64位，Windows Vista (build 6000) 64位，Windows Server 2008 R2 (build 7600) 64位。

您可以设置多个符号路径，以便调试器可以从多个位置获取符号。

.Symfix

是运行的第一个命令。然后使用

.sympathy+ c:<My_symbols>

上面的另一个问题是

Couldn't map image from disk.

我会再复制一个文件，并将你的符号路径指向那个文件，看看调试器是否可以从那里加载它。

解决了客户端操作系统附带调试器的再现问题。
